1 sticker costs $2.
1 packet of 25 stickers costs $40.
Adam needs 79 stickers.
- What is the minimum number of packets that Adam should buy?
- How much will Adam spend?
(a)
Sets of 25 stickers
= 79 ÷ 25
= 3 r 4
Minimum number of packets that Adam should buy = 3
(b)
Amount that Adam has to spend to buy 4 stickers
= 4 x 2
= $8
Amount that Adam has to spend on 3 packets
= 3 x 40
= $120
Total amount that Adam has to spend
= 120 + 8
= $128
Answer(s): (a) 3; (b) $128
